Upgrade fails on gphoto2

[gert5]

Hi All,

On a Linux machine running 'Ubuntu 14.04.5 LTS' that I haven't used a while I have the gphoto2 tool (http://gphoto.org/)
The tool tells me this is its current version:


$ gphoto2 -v
gphoto2 2.5.3

This version of gphoto2 is using the following software versions and options:
gphoto2 2.5.3 gcc, popt(m), exif, cdk, aa, jpeg, readline
libgphoto2 2.5.3.1 all camlibs, gcc, ltdl, EXIF
libgphoto2_port 0.10.0 gcc, ltdl, no USB, serial without locking

Checking the tool's home page. http://gphoto.org
(http://gphoto.org/)
It says that the current version is : libgphoto2 and gphoto2 2.5.20

I tried
sudo apt-get dist-upgrade -f and it did tons of wonderful things.

But still the version of gphoto2 is 2.5.3. (not 2.5.20)

What's the trick?

Thanks,
Gert
